Minerals of the sulfide class are compounds which contain the nonmetallic element sulfur in combination with atoms of a metal or a semimetal Compounds in which anions of antimony Sb arsenic As selenium Se or tellurium Te replace the sulfur anion and bond with metallic or semimetallic cations are classed respectively as antimonides arsenides selenides and tellurides The Elements which include over one hundred known minerals are a diverse class when taken as a whole Most of this diversity however is due to the diversity of the Non metals Subclass The Metals Subclass and related metal alloys contains metals whose properties are rather similar due to the common way in which they crystallize and bond The greatest difference in the metals is c

32 Formation of Minerals Minerals form when atoms bond together in a crystalline arrangement Three main ways this occurs in nature are 1 precipitation directly from an aqueous water solution with a temperature change 2 crystallization from a magma with a temperature change and 3 biological precipitation by the action of organisms Nonmetallic minerals are minerals that have no metallic luster and break easily These are also called industrial materials and are typically some form of sediment Nonmetallic minerals are not malleable Sand limestone marble clay and salt are all examples of

In chemistry a nonmetal or non metal is a chemical element that mostly lacks the characteristics of a metalPhysically a nonmetal tends to have a relatively low melting point boiling point and densityA nonmetal is typically brittle when solid and usually has poor Minerals of the sulfide class are compounds which contain the nonmetallic element sulfur S in combination with atoms of a metal or a semimetal Compounds in which anions of antimony Sb arsenic As selenium Se or tellurium Te replace the sulfur

Rocks and Minerals A rock is a combination of one or more minerals Metals and nonmetals are separated from impurities in the ore by a process called SMELTINGLecture series SGL 201 Principles of Mineralogy 68 Pleochroism Some colored minerals change colour between two extremes when the microscope stage is rotated The two extremes in colour are each seen twice during a complete 360 o rotation

In general the combination of a metal and a nonmetal produces a salt A salt is an ionic compound consisting of cations and anions Most of the representative metals do not occur naturally in an uncombined state because they readily react with water and oxygen in the airManganese is a chemical element with symbol Mn and atomic number 25 It is not found as a free element in nature it is often found in minerals in combination with iron Manganese is a metal with important industrial metal alloy uses particularly

The nonmetal sulfur S and the semimetals selenium Se and tellurium Te consistently play the electronegative anionic role in their compounds However the semimetals arsenic As and antimony Sb may either play the anionic role often filled by sulfur or else act as a cation by donating electrons and forming a compound with sulfur32 Formation of Minerals Minerals form when atoms bond together in a crystalline arrangement Three main ways this occurs in nature are 1 precipitation directly from an aqueous water solution with a temperature change 2 crystallization from a magma with a temperature change and 3 biological precipitation by the action of organisms
